Directions:(1-5) Find the wrong term in the series given below.
1. Question
211, 213, 219, 237, 281, 405
The next term is obtained by adding the number to the product of its digits.
211 + 2 = 213
213 + 6 = 219
219 + 18 = 237
237 + 42 = 279
279 + 126 = 405
2. Question
30, 39.0, 50.7, 67.91, 85.683, 111.3879
The pattern is as follows:
30 x 1.3 = 39.0
39.0 x 1.3 = 50.7
50.7 x 1.3 = 65.91
65.91 x 1.3 = 85.683
85.683 x 1.3 = 111.3879
3. Question
77, 303, 475, 595, 677, 727
The pattern is as follows:
77 + 152 + 1 = 303
303 + 132 + 1 = 473
473 + 112 + 1 = 595
595 + 92 + 1 = 677
677 + 72 + 1 = 727
4. Question
76, 140, 110, 124, 116, 120
From the 3rd number, each successive term is average of previous 2 terms:
(76 + 140)/2 = 108
(140 + 108)/2 = 124
(108 + 124)/2 = 116
(124 + 116)/2 = 120
5. Question
77, 126, 164, 166, 202, 206
The next term is obtained by adding the number to the square of the last digit of the previous number.
77 + 72 = 126
126 + 62 = 162
162 + 22 = 166
166 + 62 = 202
202 + 22 = 206
Directions:(6-10) What should come in place of the question mark (?) in the following number series?
6. Question
20, 56, 110, 182, ?
The pattern is 4×5, 7×8, 10×11, 13×14, 16×17
7. Question
5, 6, 14, 45, 184, ?
The pattern is,
(5+1) X 1 = 6, (6+1) X 2 = 14, (14+1) X 3 = 45, (45+1) X 4 = 184, (184+1) X 5 = 925
8. Question
41, 45, 65, 95, 140, ?
The next term of the series is generated by adding the product of the digits of the number to the number. For example,
41+4=45, 45+20=65, 65+30=95, 95+45=140
So the next term will be 140+0=140
9. Question
2744, 3375, 4096, 4913, 5832, ?
The series is 143, 153, 163, 173, 183, 193.
Hence the next term is 6859
10. Question
7, 109, 194, 262, 313, ?
The successive differences between the terms are 102, 85, 68, 51, 34.
Hence the next term will be 313+34 = 347
